INsnCT TRAP.

Application1ed'Ju1y`29; 1925; Serial No. 46,814'.

residing at Brooklyn, in the city' of New` York', county of Kings,Stateof New York, have invented certain `new and useful Inrprovements inInsect Traps,-of which `the following is a specification.

This inventionrrelates to insee-t; trapsfand more particularly todevices off'this character which, while being fully accessible'- tobugs, fiies and other insects, are provided with a covering acting as ashield to prevent the viscous' layer which is spread overr thesurface-of-v the operative part of the device fromv coming intocontactwith outside objects. Y

The'primary object of; this inventionisto provide? an insect trapofyanovel and improved construction, comprising a core "covered with somesuitable viscous. material adaptedtopreventthe escape of any insectthatshouldV venture'upon said; core, and a'- per-forated shielddetached/from said core entirely surrounding it, permittingy bu'gslandfother insects to enter the trap and; at" thesame time permittingj thesafe handlingand' laying zof the trap any-where without` danger oftheviscous material comingV in contact` with the hands orclothing;

AnotherA object of this invention is to v pro-.p videan insecttrap ofasimple and convenientdesign, adapted to be readily taken apart for thepurpose-ofrenewing the viscous layer which is used to catch bugs, fliesV and otherinsects.

Other objects andadvantagesof the pres-l ent invention will more fully'appear as the description proceeds and will beset forthy andclaimed inthe appended'claims.

Our invention is illustrated in the accompanying drawings in which Fig.l1, is laview in elevation of thev assembled dev-iceL pro,-

vided with a stand and also -prov-ided'witli al hook for its suspension;v

Referring tofF'igs; 1 to l, 10- designatesa longitudinal V4core whichvma be# made of wood, upon which are secure at theothervend coreisfinserted a tubular papenmemher 13,

memberl is inserted inpositionI as show-n in Fig. 2". Afterinsertiomthis tubularcov-ly ering is spread with a suitable viscous'material offthe kind commonly. used in insect paper` such as Tanglefoot andthe like.

The core is then providedfwith a suitableY for instance, a coveringyperforated covering,

aly plurali-tyof wirey loops l1', attached'at onefe'ndf-asat 1 2vr Y tothe core-andv slightlyfproj ecting outwardly from4 sa-idj core. Oversaid f such as 16 made ofopen wire netting-which extends almostfor theentireljength' of theVv core, and-l the diameter offwhieh isvconsiderably larger than that of' the corey so as to' leavean annularspace between the core ofy the shield, allowing ample room for-chapassageofg bugs andinsects of ordinary/size. An-vinsect" alightingf onthe'shield will inL stinct-ively' crawl through the` openings"V iny.said shield and Walk'alOngfthe'innersur# face and willV eventually comeacrossyone or the other ofithefw-ire loops with the paper coveringrvlugs, one end" of which isdetached from the core asstated, coming nearenough to the inner-surfaceof the shield to be'vvithin reach of any bugor insect walking along said inner surface. The insect'` will, there-`fore, move over to the core being attracted to it bly the smell and bythetaste of the viscous material, and will, thereforebecome entangledand caught by said material which l will prevent its escape.

The outer shield is heldin position vbe-l tween a pedestal or endbase'l? and acoverk 18 at the other end in any suitable manner. Aconvenient way of assembling ythe device is illustrated in thedrawings,inwhicliit is. seen that'each end of the core 10 is provided with aymetallic cap 19, the endface of which is formed with two segmental'slots 20, terminating in an opening 21,. of a diameter larger than thewidth of the slots. The pedestal or base 17, is in 'its-turn pro# icsvided with a cup like member 22, the inner diameter of which is the sameas the outer diameter of the shield. 'Ihe bottom of said cup member isprovided with two screws or rivets 23, 24, adapted to register with andto be inserted through openings 21, as shown in Fig. 2. In other words,the slots 2O and screws or rivets 28, 24 provide a bayonet joint betweenthe pedestal or base and the core, because after inserting the screws orrivets 23, 24 through the openings 21, the core may be turned around acertain 'angle causing the stems of the screws or rivets 23, 24 to enterthe slot part 20 pr per of the segmental slots, which will thus securelyinterlock with said screws or rivets.

In the same manner, covering 18 is provided with screws or rivets 23,211 adapted to interlock with slots 2O at the other end of the core.Said cover 18 has a cup like outline and the diameter of its edgeportion is such as to permit insertion of the cover upon the other endof the shield. The pedestal member of the cover therefore, acts aspositioning member for both the core and the shield while the core actsas the connecting member holding the various parts together.

The device may be laid upon a table, remaining supported by the pedestalof base member 17 in a vertical position or else it may be suspended ina suitable place by means of a hook member 25, which may be attached tothe cover. However, the device is also particularly well adapted forinsertion under the covers of the bed in order to catch bedbugs or inclosets or drawers where linen is kept, because the shield constitutes aprotection preventing actual contact between the viscous material andthe linen. For this reason, the hook member 25 is made removable and ahandle of any suitable' form may be substituted for it, as a more'convenient means of handling the device for these purposes. A handle ismore suitable for the insertion and removal of the device from a bed ordrawer and at the same time, the danger of tearing linen by means of thehook will be removed.

The device may also be made to be supported at the two ends in ahorizontal position as shown in Fig. 5. rIhe construction of the deviceshown in said figure is substantially the same as previously describedwith the difference that the core 2G and the shield 27 are positionedand supported by two end supports 28, 29 which permit of laying thedevice upon the table or upon the fioor underneath cupboards and thelike, in a horizontal position. This makes it easier to catch such rndsof insects like cockroaches, that dwell in dark corners and in` cracksunder the furnitui'e and which do not fly but walk or crawl. Theseinsects are apt -to be larger in size than flies and small bugs andtherefore it will be preferable in this case to make the shield of wirenetting having a sufficiently large mesh asshown in the drawing. Ofcourse, expanded or perforated metal may be used instead of wire nettingif preferred.

The paper used for the tubular covering is preferably dark green andlcrinkled so as to have the appearance of moss or vegetable mattertowards which insects are apt to be more strongly attracted.

rI"he paper tubular member is 4quite inexpensive and ther-efore may bechanged as often as desired. The viscous layer, as stated, is preferablyspread after the paper tube has been set in position. rl`he wire nettingof which the shield is made is prefer-- ably stift' enough so that itcannot easily be crushed or deformed.

The device described lends itself to various obvious modifications whichdo not constitute departures from the scope of the invention. may bemade of glass or else it may be made with perforations to afford thepossibility of internal lighting by means of a small elec-tric bulb, tocatch those insects such as moths, that are particularly attracted bylight. The same object may also be attained by making the core with apolished or light reflecting surface and adapted therefore, to reflectthe light produced byl an external source.

Another possible modification consists in making the core out of 'sheetmetal with the projecting parts such as 15 integral therewith and inspreading an adhesive coating directly upon the surface of the core. Inthis case, the adhesive coating may be renewed by first burning ordissolving in a suitable solvent, the coating formerly used.

The drawings, are therefore, intended for illustrative purposes only andnot in a limiting sense, and accordingly, we reserve ourselves the rightto carry our invention into practice in all those ways and manners whichmay enter fairly into thc scope of the appended claims.

We claim:

1. In a device of the class described, the combination with a. coremember carrying an adhesive coating, of a shield member having openingspermitting insects to reach said core member, said shield member leavingan annular space around said core member suflicient for the passage ofsaid insects, and parts projecting from the surface of said corel membertowards the inner surface of said shield member, to points within thereach of insects within said shield member.
